Title:
SERS SUBSTRATE FOR DETECTING SYNTHETIC PIGMENT AND RAMAN DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/186834
Kind Code:
A1
Abstract:
Disclosed are a SERS substrate for detecting synthetic pigments and a Raman detection method. The SERS substrate comprises a base plate, precious metal nanoparticles provided on the base plate, and a modification layer used for grabbing synthetic pigments on the surface of the precious metal nanoparticles. The modification layer is composed of modified molecules, and the modified molecules are a combination of one or more selected from among C2-C12 hydrocarbyl compounds substituted by thiol and amino groups and salts thereof. The SERS substrate above is used for a method for detecting synthetic pigments. The present invention does not require that a sample be pre-treated, may directly grab illegal additives (i.e., artificial synthetic pigments) in the sample for detection, and then obtain a surface enhanced Raman scattering pattern thereof. The present invention is quick and efficient and has high detection sensitivity.
